Cowart Open Canvas (Vetta 1:1)
Host mapping
| Codex | Vetta |
|---|---|
MCP App widget (ui://widget/...) |
Activity panel tab with full tldraw App |
window.cowartMcp bridge |
Plugin installs the same bridge via ctx.fs + conversation.sendPrompt |
| Canvas files under project | <projectDir>/canvas/ (shared with MCP tools) |
Workflow
- Call plugin tool
open_cowart_canvas(opens the Cowart activity tab at max width). - Optionally call MCP
render_cowart_canvas_widgetwithprojectDir= user workspace to confirm storage paths. - Canvas data:
canvas/cowart-canvas.json
canvas/pages/<page-id>/cowart-canvas.json
canvas/pages/<page-id>/assets/
canvas/cowart-selection.json
canvas/cowart-view-state.json- User draws/annotates in the panel. Agent uses MCP tools (
get_cowart_*,insert_cowart_image, …) for programmatic canvas IO. UI AI actions send follow-up prompts into the active conversation.
Image tools (when UI / user asks for bitmaps)
| Intent | Tool |
|---|---|
| New image | generate_image |
| Edit / annotation revise | edit_image |
Then place with MCP insert_cowart_image. Do not use an imagegen skill.
Constraints
- Never pass the plugin install directory as
projectDir. - Prefer
open_cowart_canvasfor the interactive UI; MCP tools remain available for agent-side canvas edits.
